Lead acetate Light, polarized

The platinized platinum electrodes were prepared by electrolyzing a solution of chloroplatinic acid containing no lead acetate (23). The metal deposition was stopped as soon as a light brown color appeared on the platinum wire. They were then immersed in IN H2S04 and electrolyzed again their polarity was alternated every 2 minutes for 20 minutes. The platinum electrodes were washed thoroughly with distilled water and soaked in conductivity water for one week before they were used.
